Pemanfaatan Data Penginderaan Jauh dan Sistim Informasi Geografis Untuk Identifikasi Perkembangan Lahan Terbangun pada Wilayah Rawan Gempa Bumi di Kota Ambon

Abstract

Earthquakes are natural disasters that often occur in Indonesia, including in Ambon City which is located in an earthquake-prone area. This research aims to identify the development of built-up land in earthquake-prone areas in Ambon City by utilizing remote sensing data and geographic information systems. This research uses data on built-up land in Ambon City in 2019 and 2023 as well as earthquake hazard maps. The results show that built-up land in Ambon City in 2013-2023 experienced a significant increase in area from 4,718.17 ha in 2013 increasing in area in 2023 to 6,762.57 ha. The area of built-up land located in earthquake-prone areas in Ambon City has a relationship that is directly proportional to the year of development of built-up land. So that as the year increases, the area of built-up land located in earthquake-prone areas also increases. The results of this research are expected to serve as a basis for developing policies and mitigation strategies aimed at the sustainability of the Ambon City area amid the existing earthquake threat.
